 Thanks , doc . I ’ Ve got a really bad toothache ! I can ’ t eat anything , and look , my face is all swollen . I think it might be my wisdom tooth . 
 Well , let ’ s have a look . Open wide . Hmm ... this doesn ’ t look good . Well , it looks like you have a cavity and your crown is loose . We ’ ll need to put in a filling before it gets any worse , and the crown probably needs to be refitted . I ’ m going to order some x-rays .
